Release 5

Summary of changes:

• Update video ram controller to fix an earlier design error and add a noise killer
• Reduce Config Clk from 20MHz to 10MHz
• Resync with IceBoot 0.4 and update version string
• Increase speed of config from FLASH 4x using buffered SPI writes

Note: Reducing the config clock to 10MHz has got rid of the sporadic CDone Not Set errors I was seeing on my BlackIce II board.

Release 4

Summary of changes:

• Updated sddos to cb0f952d - Added cmd58 (Read OCR) to confirm HC support
• Updated sddos to ff05af19 - Extend response delay from ~12ms to ~200ms
• IceBoot: enable mux during bitstream load from flash, for some reason not doing this results in CDONE not set errors

The first two changes fixed some issues with certain MicroSD cards.

The final change helps prevent a "CDONE not set" error on BlackIce-II
